4 Claim.

This invention relates to certain new and useful improvements in bottle caps designed more especially for use with milk bottles and the like of the usual form. The invention relates more particularly to bottle caps-of the class having a central circular portion adapted to fit into the neck of the bottle and an annular flange adapted to fit over the edge of the bottle to form a sanitary seal over the bottle opening.

The main object of my invention is toprovide in a bottle cap of-the class described a means formed integrally with said flange for preventing the nesting of said caps when stacked for storage or for use in a bottle capping machine.

The bottle cap of my invention is illustrated in the accompanying drawing, in which:

Figures 1 and 2 are, respectively, perspective views of the paper disks or blanks from which the cap is pressed or molded.

Figure 3 is a plan of the finished cap as seen from above.

Figure 4 is a section taken on line 4-4 of Figure 3 showing the cap of Figure 3 stacked on a similar cap.

Figure 5 is a perspective view ofmy cap as applied to a milk bottle.

Figure 6 is a section taken on the line 5-6 of Figure 5 showing the cap as applied to the milk bottle and a portion of .the milk bottle neck, the lower part of the bottle being broken away.

The body of my cap is formed from a circular disk or blank 10 of paper shownin Figure l, and the central portion is reenforced by a circular disk ll illustrated in Figure 2. The construction of the cap is perhaps best seen from Figure 4. The body of the cap comprises a central portion I2, an annular bellows fold l3 and an annular U-shaped flange H, the lower edge l5 of which terminatessubstantially in the plane of the central portion l2 before the cap is applied to a bottle. The bellowsfold i3 overlies the edge of the reenforcing disk II and secures it in place against the central portion l2. The flange I4 is adapted to fit over the top edge of a milk bottle 16, as shown clearly in Figure 6.

In forming the cap, a plurality of inwardly projecting beads I1 are formed integrally with the inner wall of the flange it. These beads. H are arranged at substantially equal intervals around the inside perimeter of the flange I4, as clearly shown in Figure 3. The beads I1 are formed with the tops l8 thereof spaced below the plane of the top of the flange It at such a distance that when a second cap is placed upon the first cap the central portion 12 of the second cap .the central portion,

will rest-upon the tops ill of the beads I! so that the lower outer rim l5 of the flange I4 is prevented from slipping down over the flange of the bottom cap, thus preventing the caps from nesting one in the other.

Although I have shown and described a speciflc construction of cap as constituting an embodiment of my invention, I wish to be limited only by thelscope of the appended claims.

I claim:

1. A bottle closure comprising a disk of pliable material having a body portion adapted to fit the recess in a milk bottlemouth and an annular bellows fold overlying'the body portion, said bellows fold being provided with an extension having a surface for contact with the upper edge of the bottle, said extension being provided with a circular flange extending substantially axially with respect to the body portion and normally terminating in a plane substantially coincident with the plane of the body portion, and a plurality of inwardly extending beads formed on I said extension wholly between the bellows fold and said contact surface to form supporting surfaces for the body portion of an adjacent cap when the caps are stacked.

bottle, and a plurality of inwardly extending beads formed 'on said extension wholly below said contact surface to form supporting surfaces I for the body portion of an adjacent cap when the caps are stacked.-

3. A bottle cap comprising a disk having a central portion adapted to fit the recess in a milk bottle mouth, an intermediate portion extendingupwardly from the central portion to form an annular extension having a substantially smooth continuous surface for contact with the upper edge of the bottle and a marginal portion extending downwardly from said extension to form a circular flange arranged substantially co-axially with respect to the central and intermediate portions and normally terminating in a plane substantially coincident ,with the plane of and inwardly extending means formed on the intermediate portion wholly below said contact surface to. form a support and a marginal portion bent downwardly from said extension to form a circular flange arranged substantially co-axially with the central and intermediate portions, said flange normally terminating in a plane substantially coincident with the plane of the central portion, and inwardly extending means formed on said extension wholly below said contact surface to form a support for the central portion of an adjacent cap when the caps are stacked.
